Product Details

The AD7091R-2/AD7091R-4/AD7091R-8 family is a multichannel 12-bit, ultralow power, successive approximation analog-to-converter (ADC) that is available in two, four, or eight analog input channel options. The AD7091R-2/AD7091R-4/AD7091R-8
operate from a single 2.7 V to 5.25 V power supply and is capable
of achieving a sampling rate of 1 mega samples per second (MSPS).
The AD7091R-2/ AD7091R-4/AD7091R-8 contain a wide bandwidth
track-and-hold amplifier that can handle input frequencies
in excess of 1.5 MHz. The AD7091R-2/AD7091R-4/AD7091R-8
also feature an on-chip conversion clock, an on-chip accurate
2.5 V reference, and a high speed serial interface.

The AD7091R-2/AD7091R-4/AD7091R-8 family offers up to eight
single-ended analog input channels with a channel sequencer
that allows a preprogrammed selection of channels to be converted
sequentially.

The AD7091R-2/AD7091R-4/AD7091R-8 has a serial port
interface (SPI) that allows data to be read after the conversion
while achieving a 1 MSPS throughput rate. The conversion process and data acquisition is controlled using the CONVST pin.

The AD7091R-2/AD7091R-4/AD7091R-8 family use advanced
design techniques to achieve ultralow power dissipation at high
throughput rates. They also feature flexible power management
options. An on-chip configuration register allows the user to set up
different operating conditions. These include power management,
alert functionality, busy indication, channel sequencing, and
general-purpose output pins. The MUXOUT and ADCIN pins allow
for signal conditioning of the multiplexer output prior to
acquisition by the ADC.

Product Details

The EVAL-AD7091R-2SDZ, EVAL-AD7091R-4SDZ, and EVAL-AD7091R-8SDZ are full featured evaluation boards designed to allow the user to easily evaluate all features of the AD7091R-2/ AD7091R-4/ AD7091R-8 family of analog-to-digital converters (ADCs). The evaluation board can be controlled via the SDP connector (J13). The SDP board ( EVAL-SDP-CB1Z) allows the evaluation board to be controlled through the USB port of a PC using the evaluation board software available for download from the product page.

Analog-to-digital converters (ADCs) have many specifications; some are more important for a given application than others. Understanding these specifications and controlling external devices affecting the ADC will lead to better performance.
